The test tube is widely used in chemistry, biology, physics to make very different experiments.

By pulling on both ends of heated glass. The more they pull, the smaller the diameter of the resulting glass tube or capillary.
I think you mean 'capillarity' which happens in very thin tubes because the adhesive forces between water and glass molecules is greater than the cohesive force between water molecules alone. In narrow tubes, this is enough to pull the liquid up the tube.
Different laboratories may use different color codes for test tubes depending on their specific protocols. However, a common color coding for test tubes used in centrifuges is as follows: red for serum tubes, lavender for EDTA tubes, green for heparin tubes, and blue for citrate tubes.
The specimen is usually the glass particle in the serum separator tubes.

The Mystery of the Glass Tubes - 1914 was released on: USA: 29 September 1914
trims and sharpens edges of glass, such as glass tubes
Blood clotting in test tubes due to glass occurs when the glass surface activates clotting factors present in the blood. The glass can cause physical trauma to the blood cells, triggering the clotting process. This can lead to ex vivo clot formation in blood samples collected in glass test tubes.
glass, and blow in tubes to from shape
Scientists tools are are test tubes magnifying glass, beakers,and Bunsen burners.
1. Fluorescent tubes are filled with argon; neon is only an old legend. 2. The coating is not the same for all the tubes. For details see the link below or ask the plant which produce the tubes.

to clean all glass and bottles for heavy metals analysis you can use acid wash nitric acid 10%, just put all your tubes and glass in acid wash over night then wash it twice with distilled water and one with D.D.W.
